There are seven genetically different types of Rabies Virus in the US, each one surviving best in a certain wildlife species. The raccoon variant infects raccoons and skunks in the eastern US and costs the government and taxpayers a lot of money every year. The most expensive aspects of raccoon rabies are the costs of vaccinating people after they experience an animal bite and the vaccination of raccoons throughout the eastern US. The USDA and other scientists from around the world are cooperating to eliminate this variant from the US. My job is to use computer simulations to determine how this can be best accomplished using different combinations of management tools, such as more intense vaccination.
